Rhubarb & Apple Crumble

Yum!
One of the best thing of living in other countries is the different fruits and classics you can do. Another classic, rhubarb crumble, rhubarb does not even exist in Spain.

I followed another BBC recipe and worked out great. 

INGREDIENTS:

For the fruit mix:
-500 grms of rhubarb.
-500 grms of apples.
-180 grms of sugar (aprox).

For the crumble:
(this crumble is for 2 pies, and you can freeze it)
-250 grms of flour.
-160 grms of cold butter.
-80 grms of oats
-100 grms of brown sugar.

STEPS:

1.  Cut up the fruit (rhubarb and apples into pieces) and coat it in sugar. 
2. Stick in oven for 20 minutes and roast, turning it every once in a while. It will caramelize a little....yes drooling. The fruit will soften and roast. 
3. Now in the meantime, make the crumble. Add the ingredients above together and dissolve with hands. The butter has to be COLD and hard. Stick in the freezer if it isn't.
4. Now transfer the cooked fruit to your pretty dish that you will use. The fruit will have shrunk so you need a smaller dish. Now add the crumble on top and be generous.
5. Stick in oven again for 20 minutes or until the crumble is golden. 

Ready! 
I find that the proportion of sugar to the sourness is the tricky part in these desserts. In my opinion the British recipes are better than American ones, which contain so much sugar you'd be running marathons, every single day to burn off. I read MANY recipes to understand that this is a pretty good proportion. Let me know what you think.
